Are you looking for a complete upper or are you planning on building it yourself?

A complete upper.

If I have to build it it may never get done like the one I already have waiting for me to do something with it, but that is for another rifle.

I can say that the Bravo Company light wieght upper is a great buy. I ditched the front site and installed a troy extreme handguard and magpull sites. Very light and a blast to shoot.

Just as a heads up, it would seem that Magpul's MBUS' would be the lightest sights to go with, but the fixed Daniel Defense sights are actaully a bit lighter. If you're trying to shave weight every little bit helps.

I'd also go with a Troy or VTAC tube for a forend, and shave a A2 sight down to bare minimum.

Not super lightweight but fairly light.

Bravo Company 16'' lightweight upper with carbine gas $385 or $520 with bolt and charging handle.

Just leave the standard front sight base and use the Magpul MOE handguards. If you really want a rail get a 7" DD Omega.

I dont want a full rail forend. I ordered the Magpul BUIS set for it so I need a gas block with a rail to mount the front sight.

Don't mount your front MBUS on a gas block.

You need the standard front sight base for those handguards. Just return the front Mbus or sell it.

Magpul does not recommend mounting their MBUS' on a gas block due to heat and how it affects the MBUS.
Also remember to not tighten them down too much.

It's done! Any suggestions or opinions on knocking off some more weight? FBA removal???

Anyone ever heard of a lightweight flash suppressor?

In my opinion if you want light weight you will have to do without a forearm rail just the standard forearm coveres. typically those rails add weight unless you get a carbon fiber one see below.

I am building a light weight rifle for my wife. I just purchased an adam arms 16 inch standard upper it weighs 4.32 pounds. You can pick one up for around $550. There are probably lighter options out there but I went for this one because of the gas piston system i just prefer them they require less cleaning (A gas piston system adds weight). You might consider getting an upper with a 14 inch barrel with a pinned muzzle break as long as it meets the minimum barrel length requirements.

If you want a railed forearm then there are carbon fiber options that weigh 13 oz including barrel nut.

Usually Del-ton has them at a good price (around $90) with buffer tube, buffer and spring:

Lower receiver:

There is not much you can do with the lower if you want to use a metal lower but if you don't mind using plastic well there are the Plum Crazy lowers to consider.

After all the big items stock, upper, lower. Then consider the smaller stuff.

For example use a light weight buffer, use plastic sights (magpul) etc... all these little things add up. The more toys and furniture you add to your rifle the heavier it gets.

Just my opinion

Pal, are you sure about that, just looking at it it seems I could change it out for something else and still use this handguard?

I am not saying that you cannot have a handguard there are many options out there for plastic ones. Even the standard A4 hand guards are light. What I was infering is that you what a railed forearm/hand cover like daniel defense etc... they add at least a half a pound to the rifle. Then you are bound to add attachements to the rails that will also increase the weight.
